Jumunjin Seafood Market is Gangneung's busiest northern fish market, set by the port where the day's catch comes in from the East Sea. Stalls sell fresh fish, shellfish, dried seafood, and raw fish meals, so it works both as a shopping stop and as an easy lunch detour.
The market is most interesting in the morning, when the port is active and the displays are full. It is north of central Gangneung, so plan it with Jumunjin Beach or the coast road rather than as a quick walk from downtown.
